As a kid, I thought all pudding not in 'pop' form was meant to be eaten warm. Except pistachio because pistachio pudding is always chilled. This is probably why I do not care for pudding pies. Chilling butterscotch pudding is an abominable crime that should not be tolerated. I do tolerate the chilled puddings 'cause that is how K. prefers them and chilled pudding people tend to be more particular about their preference, in my experience. Room temperature pudding is just wrong. Something about the texture with little discernable temperature difference on the tongue that is unpleasant to me. Luckily, pudding is easy enough to make that pre-made pudding cups have not been allowed in the house in a while.
Favourite pudding: tapioca. The real stuff, not that fake instant-pudding-with-tapioca-added crap.
